Dear, my domain is "example.com". My cooperative mail server is an Exchange which does not implement DKIM at all.
But also I have a Postfix mail relay for the "example.com" domain. Is it possible to implement DKIM only in my Postfix server for all the outgoing @example.com mails ??? Or doing this I affect the outgoing mails from my Exchange server because it sends @example.com mails withouth DKIM mechanism ??? Thanks a lot !!! Robert
